The handles are tubes and are easy to rub down to smooth prior to painting.The grassbox is not easy.I find the inside is the most hassle.I use primer/filler rubbed down to smooth to get finish I want.Spraying the inside takes time and a lot of spray comes out via back draught.The time taken to get it perfect will reflect on the finished box.

Right now everything's at a halt as Im trying to get the roller gear off. Im going to use a puller since any careful leverage ends up flexing the aluminum and nothing else. The other gears came off no problem.
